Linux Kernel Multiple Vulnerabilities

Release Date: 21 Oct 2021 1806 Views

RISK: Medium Risk

TYPE: Operating Systems - Linux

TYPE: Linux

Multiple vulnerabilities were identified in Linux Kernel, a remote attacker could exploit some of these vulnerabilities to trigger denial of service condition, elevation of privilege, remote code execution and sensitive information disclosure on the targeted system.


Impact

  • Denial of Service
  • Remote Code Execution
  • Information Disclosure
  • Elevation of Privilege

System / Technologies affected

  • Ubuntu 21.04
  • Ubuntu 20.04 LTS

Solutions

Before installation of the software, please visit the vendor web-site for more details.

 

The problem can be corrected by updating your system to the following package versions:

  • Ubuntu 21.04
  • Ubuntu 20.04

After a standard system update you need to reboot your computer to make all the necessary changes.

 

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
